Quartz

Quartz, composed of silicon dioxide (SiO₂), is a mineral renowned for its purity, stability, and durability. Its unique properties make it essential for advanced industries such as electronics, optics, and high-performance manufacturing.

Since 2010, MidAtlantic has developed expertise in sourcing, developing, and processing quartz using advanced washing, optical sorting, crushing, screening, drying, and purification technologies. This end-to-end mastery allows us to supply high-purity quartz for demanding markets.

Our premium quartz products, distributed under the MID-40™ and MID-325™ brands, are derived from crushed quartz gravel and meet the highest standards of purity and performance.
